April 11, 2022, 1:47 a.m. Updated 35 {"title": ["", "High Fidelity Modelling of Wind Turbine Main-Bearing Operational Loads"], "description": ["", "\nState of the art design methodologies for turbine main bearings are still entirely focussed on linear fatigue theory. The very high rate of failures seen in the field seem to be a clear indication of the unsuitability of this linearity assumption. However, there does not currently exist an alternative metric by which more complicated failures, resulting from shock loading and wear, can be expressed in a statistical sense from which expected lifetimes may be determined. The extension of existing theory to account for realistic loading conditions experienced by wind turbine main-bearings has huge scope to lower the levelised cost of energy since it would allow for improved lifetime prediction, the development of new and more sophisticated testing procedures for bearing certification and would certainly contribute to improvements in design methodologies. \nThis PhD will therefore initially develop high fidelity FEA models of various wind turbine main bearing designs before applying them in order to study in detail the possibility for one of the following outcomes (chosen by the student):\n-Development of main-bearing dynamic damage metrics and remaining lifetime prediction approaches\n-Development of new procedures for main-bearing testing and certification which account for realistic dynamic loads (including accelerated testing)\n-Main bearing design analysis based on realistic loading, including comparisons of existing designs and the development of new solutions to reduce harmful loads (e.g. the potential for additional mechanical damping).\n\n"], "extra_text": ["", "\n\n\n\n"], "status": ["", "Active"]}
